Five vascular diseases linked to one common genetic variant

Genome-wide association studies have implicated a common genetic variant in chromosome 6p24 in coronary artery disease, as well as four other vascular diseases: migraine headache, cervical artery dissection, fibromuscular dysplasia, and hypertension. However, it has not been clear how this polymorphism affects the risk for so many diseases. Researchers show how this DNA variant enhances the activity of a gene called endothelin-1, which is known to promote vasoconstriction and hardening of the arteries.

Screening for vascular disease saves one life for every 169 patients assessed

A novel screening program for vascular disease saves one life for every 169 men assessed, according to new research. The combined screening for abdominal aortic aneurysm, peripheral artery disease, and hypertension gained more living years for lower costs than European cancer screening programs.

Novel PET tracer detects small blood clots

Blood clots in veins and arteries can lead to heart attack, stroke, and pulmonary embolism, which are major causes of mortality. Now researchers show that targeting GPIIb/IIIa receptors, the key receptor involved in platelet clumping, with a fluorine-18 labeled ligand is a promising approach for diagnostic imaging.

Midlife cardiovascular risk factors may increase chances of dementia

A large, long-term study suggests that middle aged Americans who have vascular health risk factors, including diabetes, high blood pressure and smoking, have a greater chance of suffering from dementia later in life.

Nanoscale forces measured in aortic smooth muscle cells tell story of disease

Researchers have collaborated to employ a novel nanoscale fibrous system that can measure the tiny forces exerted by and upon individual cells with extreme precision. The team hopes that this platform, which investigators call nanonet force microscopy (NFM), will provide new knowledge about smooth muscle cell biology that could have implications for treating cardiovascular disease, which is still a leading cause of death in the United States.

Study shows arteriovenous fistula can be created with magnetic technology instead of open surgery

A new, minimally invasive system which uses radiofrequency energy instead of open surgery to create arteriovenous fistulas for patients needing hemodialysis, is reliable, with minimal complications, according to data published in the American Journal of Kidney Disease.

Vascular Health: Millions at Risk for Peripheral Arterial Disease

The condition occurs when sticky plaque that builds up in the arteries hardens and blocks the vessels, limiting the flow of oxygen-rich blood to the limbs.

Adolescent obesity linked to early mortality from cardiovascular diseases

While there is solid evidence that adolescent overweight and obesity are associated with coronary heart disease (CHD) and stroke, less is known about the association between body mass index (BMI) and rarer cardiovascular diseases.

Diabetes: Heart attack risk due to loss of small blood vessels around the heart

People with diabetes have a significantly higher risk for heart attack. Now, new research suggests that diabetes damages the small blood vessels around the heart, and this might explain the link to heart attack. In a study reported in the Journal of the American College of Cardiology, the researchers also propose a solution may lie in gene therapy.
